I really want to Preorder TTK. I have 360 & XB1 & I play both. If I preorder for the XB1, will I also have to order the 360 version when it comes out? If I order just the 360 versions (is there going to be a 360 preorder version) will I be able to download the XB1 Next Gen version free? (like when Destiny was first released) Lastly, if I preorder the Digital Download for current owners, do I get COLLECTOR'S EDITION EXCLUSIVES as well as the Year One Exclusives?
